Something's wrong with your app. Let's stop it today.
I'm a software engineer who locks down apps built with Lovable, Bolt, Cursor, Replit and v0. I find how they got in, close it, and explain what happened in plain English.

Paid up front once you've said yes. The goal is to have you locked down within 24 hours of starting.
I'm Nate Parker, a senior software engineer. I've taken three clients through live security incidents.
Do these three things right now
They're free, and they buy you time whether you hire me or not.
- Replace every secret keyOpenAI, Stripe, Supabase, anything in your settings. Make new ones and delete the old ones.
- Set a hard spending capYour AI provider and your hosting both have one. Set it low today. Raise it later.
- Don't delete anythingLogs and old code are how I find the way in. Wiping them hides the hole. It doesn't close it.
What I do once you book
- Find the way inI read the code, the database rules and the logs until I know exactly how it happened.
- Close it properlyThe hole gets fixed and tested, and I check for the same mistake everywhere else in the app.
- Tell you what was touchedWhich data, which accounts, how much money. No guessing.
- Write it up in plain EnglishA short summary you can forward to customers, a co-founder or a lawyer.

Why it's $1,500
One price, whatever I find. No meter running while you panic, and no minimum engagement. If it takes longer than I thought, that's my problem, not your invoice.
Figures from freelance security consultant rates. Not my former prices: I have never charged them.
Who you're hiring

For five years I've built and defended the platform at a healthcare software company, where security is a large part of my job. I'm also the security engineer for a B2B software startup, and I've found real vulnerabilities in widely used open-source code. I've built, shipped and sold my own software too, so I know what it's like when the app is your income. You work with me directly.
Across my professional security work, not App Locksmith alone. The clients are under NDA, so no names, ever — including yours.
